F. von Langsdorff Bauverfahren GmbH was founded in Germany by veteran engineer Fritz von Langsdorff in 1964 in order to license a new interlocking concrete paver shape - the original UNI-STONE®. Little did he know that in subsequent decades it would become the world's most successful concrete paver shape.
The use of segmental paving has a long history and can be dated back more then 5,000 years to the Minoans on the island of Crete, but it was not until the advent of precast concrete pavers that their use became commonplace. These modern pavers, with their tight dimensional tolerances and increased structural strength, made it possible to offer designers alternatives in terms of better performance, pleasing aesthetics and lower costs. The invention of the shaped interlocking concrete paver in Germany, especially the UNI Product Line, had tremendous success and in the 1960s a period of rapid growth commenced within the German UNI Licensing Group.
Soon after their initial introduction in Germany, UNI Pavers were licensed in other countries. These unique pavers was introduced to North America in 1973, heralding the founding of the UNI-GROUP U.S.A. In 1983, the Canadian office known as F. von Langsdorff Licensing Limited was established in Toronto to better serve the needs of the North American Licensee. It is now headed by Harald von Langsdorff, the son of Fritz von Langsdorff.
In 1989, F. von Langsdorff Licensing brought the first permeable interlocking concrete paver (PICP) to North America with the introduction of UNI Eco-Stone®. SInce then, Harald has expanded the permeable product line with the introduction of several other patented products - Ecoloc®, Eco-Optiloc® and Eco-Priora®. For more than 25 years, the Eco-Stone Family of Permeable Pavers have been the choice of engineers and other design professionals for residential, commercial and municipal applications across the country.
Congratulations to Harald and F. von Langsdorff Licensing on serving the world-wide interlocking concrete paver industry for 40 years!Congratulations to ICPI on 20-Year Anniversary
Greenroads is a sustainability rating system for roadway design and construction. It is applicable to all roadway projects including new, reconstruction and rehabilitation (even overlays), bridges, you name it. If it is a project where a road is involved, you can use it.
Greenroads is a collection of sustainability best practices, called "credits," that relate to roadway design and construction. Achieving these credits can earn points toward a total score for the project, and in general, this Greenroads™ score can be used as an indicator of sustainability for the roadway. Four different certification levels (rating) are available depending upon total score on a voluntary basis.
